To all whom it may concern: 1

Be it known thatl, WILLIAM L. DEN'CI-I, a citizen ofthe UnitedStates, residing at..Pelham, in the county of Westchesterand State of New York, have invented a new and useful'Register for Adding-Machines, of which the following is aspecification.

ion

. This invention relates to fractionalregia ters 1n general, but-more, particularlyfto registers of that type employed in combined to :typewriting and addinginachines, as for instance, what is known to commerce, as. the i Elliott-Fisherhilhng machine, exemplified in Patents Nos. 820,879 and 82.9

,971 to Charles F. Laganke and John A. Smit The object of the invention is to provide anovel' arrangement: of parts whereby the reading of the registered value is facilitated. 1 In registers of the character specified,

digits onthe peripheries of a series of num- "ber wheels are displayed opposite a, sight :0. ening in theregister casing. "Heretofore t jese numbers-have been arranged in alinean; arrangement is liable to cause j ment and their significance has vnot been value of readily a parent, although the abstract the number has been obvio'us. It has been proposed to-construct a register Whereinone or more of the registering wheels will represent fractional values, but so far IamaW-are, i edisplayed digit, 01w" onal 1th the digits representinglthe whole n inh ch in the reading of the registered value:

" In accordance with my present invention,

it is contemplated to register the whole numher-and the fraction in a manner-which swill make-a display substantially like that made and the digits on the peripheries of t' e sev:

era'lg'number Wheels, are so arranged thatthe digits representing the whole nuniherfw'ilt appear in alinement opposite the lower sight opening =while' the digit re resenting the numerator .of the-.fractiona value Wlll be displayed in. an elevated position opposite the upper sight openin and above a perm'ae Q nent' d enoimnat'or disp eyed on the register casing.

,In the accompanying drawings Figure 1 is a front viewot a fractional register constructed and, arrange-:1, in accordance with my invention. Fig: 2 15a SlIlllliLI VlWgWltll the upper front wall or hood of the casing in section to show niore distinctlythe relative arrangementpi' the digits on the several wheels, and Fig. 3 is a vertical longitudh naljsectional view through a portion of the register.-, Q 4 A r The register casing 1 is -equipped as usual, ;-at the upper front. corner thereof," with a -;cur ved wall or, hood 2 The hood is provided ,Wlth' a. comparatively long, horizontal sight opening 3, spaced from the righthand end of WllClLbY an interval preferably equivalent to a number space, is a second and comparatively/small sight opening 4, which occupies .a somewhat elevated positionrelativeto the opening 3. Within the casing] is mounted computing andregistering mechanism which is, general y speaking, of ordinary character, except for the relative arrangement of the digits on the peripheries of the nu ,Wheels. v

. "lhenumb and e are of corresponding diameter and are mounted Within the hood '2 on a; transverse I numberwheel shaft 5. .Thewheels b to e in,-, elusive, areiwhat areknjown as ten1ncre ri'ient wheels and display upon the outer faces of their teeth'the digits ,0. to 9 inclusive. These wire is register,' 0 posite the s ght ope whole nuin er, of which they rep? the diiierent denominations, as for instance, units, tens, hundreds and thou sands; l,

. l The wheel a, isseparated from the wheel I) by a letter space interval, and although of the same diameter as! the other number wheels, is what is known as aneight-ii icrementwheel, and registers the numerator of the fractional value. 011 the periphery of thisnumerator wheel a are displayed eight characters, to a it,tliedigits {l to 7 inclusive, since. in the present instance, tljiiswheel. is designed for. thegadditionof 'eighths. The digits on the wheel a are presented succesrnben er or registeringwheels a,-- b, c, d

sively opposite the relatively elevated trace tional sight opening a, the digits on this wheel being so. arranged, that when the wheel oomesgrto rest,=a digit-thereon will not be located in alinement with the reading line of the othenwheels, bill Will, on the contrary,

be'located in thatrelatively elevated posi- .numerator and the denominator..

tion with respect to the whole number which is usually occupied by the numerator of a fractional designation, when a whole number and a fraction are written or printed.

The denominator 6 of the fractional desi nation, in the present instance the digit 8' is permanently displayed on the front Wall of the casing, directly 'below the sight opening 4, so that the variable numerator displayed at said 0 ening will read naturally in conjunction wit the subjacent permanent denominator.

It is usual in expressing a fractional value to provide a horizonatal line between the Such a line, indicated in the drawings by 7, is therefore permanently displayed on the wall of the casing, substantially midway between the numerator and the denominator and in a plane about midway of the upper and lower edges of the whole number opening 3. In. other words, the line 7 is located op osite the center of the whole number, an the numerator and denominator are equidistantly. spaced, as usual, above and below the line, so t 1 at the whole number and fractional designations will appear in their usual and ordinary relation, and thusfacilitate the accuratereading of the registered value.. In other words, the numerator may occupy an elevated positionrela'tive to the whole number, while the denominator will occupy a relatively depressed position. It is immaterial, however, whetheror not the numerator and denominator extend above and below the whole number, since the digits expressing the fraction may be considerablysmaller than those expressin the whole number and the entire fractiona designation may therefore occupy no greater space vertically than is occupied by the whole number, the gist of the invention residing in clearly-differentiating the numerator digit of the fractional designation from the digits expressing the whole number; The numerator digit is therefore relatively elevated within the urview of this invention if a horizontal ine drawn through its center lies in a plane higher than a line drawn through the center of the whole number.

The number wheels may be operated in any suitable mannerf-as for instance through the medium of an alined series of'i'dlers 8,

adapted to be successively engaged by a master wheel mounted on and movable with the typewriter carriage, and operated by the numeral keys of the typewriter, in a manner well understood in the art and more particularly pointed out in 'thetwo patents heretofore identified.

The means whereby motion is transmitted from the idlers or operatin wheels 8 to the number wheels, the mechanism whereby values are carried from one wheel to another,

and the means whereby the resetting of the n unber wheels is effected, are not material to the resent invention and have only been genera y shown in the accompanying drawin s.

%3efore concludin it ma be stated that while the illustrated embo iment of the invention' comprehends the employment of four registering wheels devoted to the registration of the whole number, and a single registering wheel devoted to the registration of eighths, the number of wheels of either character is immaterial. It is likewise immaterial what fractional value is indicated, it being understood, however, that any variation of the denominator will be accompanied by a corresponding variation of theseries of digits on the enumerator wheel a.

It is thought that from the foregoing, the construction and o eration of my register willbe fully comprehended, and I Wish to be distinctly understood as reserving the right to effect such changes, modifications, .or variations of the illustrated structure as may come fairly within the scope of the protection prayed.

What I claim is 1. In a register of the character described, the combination with means for registering a variable whole number, of means for registering a variable fractional value with the numerator displayed in an elevated position relative to the whole number.

2. A register having a series of number wheels exhibitin 'analined series of digits representing a w ole number,-an additional wheel exhibiting a numerator in a relatively elevated position, and adenominator exhibited below the numerator.

3. In a register of the character described, the combination with a casing having sight openings in different horizontal and vertical planes, of a series of'denominational members exhibiting an alined series of di 'ts at one opening,,a member exhibiting a lgit at the other. opening, and a denominator exhibited on the casing below the opening last named.

4. In a register, the combination with a casing having a whole number sight openingand a relatively elevated numerator si ht opening beyond one end of the o ening st named, of a shaft, a series of whee s mounted on said shaft and bearing digits arranged to be exhibited at the respective sight openings, and a denominator exhibited ontlie casing below the numerator sight opening and o'ccu pying a depressed position relative to the whole number sight opening.

In testimony, that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of-two witnesses.

WILLIAM LESTER DENCH.
